Carborundum, grading

Carborundum is rjsed mainly for fast work when much glass needs to be removed, and for grinding quartz. It is cheaper and harder than emery. It can be graded by particle size the coarsest normally used is 90 mesh. The medium size is about 180 mesh, and the fine about 300 mesh, with very fine of 600 and 900 mesh this last is usually unnecessary since better results can be obtained with jeweller s rouge. Carborundum is also often graded in F numbers F consists of 240 mesh and finer 2F of 280 and finer and 3F of 320 mesh and finer. Carborundum is used in the same way as emery, and has the advantage that carborundum wheels and blocks can be obtained. [Pg.25]

Surfaces which require regrinding, such as those of stopcocks, usually fit fairly well, and a fairly fine grade of carborundum can be used for the grinding. Stopcocks must not be ground too much, or the holes in the plug wiU no longer meet those in the barrel. [Pg.46]

In both cases, the strain-to-failure increases as the creep rate decreases.
